Updating $\nu_{3}$ lifetime from solar antineutrino spectra
Updating $\nu_{3}$ lifetime from solar antineutrino spectra
We study the production of antineutrinos from the solar neutrinos due the Majorana neutrino decays of neutrino to antineutrino. Using the antineutrino spectra from KamLAND and Borexino, we present newest limits on the lifetime of $\nu_{3}$ in this scenario. We consider $\nu_{3} \rightarrow \bar{\nu}_{1} + X$ and $\nu_{3} \rightarrow \bar{\nu}_{2} …
